I forget if its 6 or 9 months cooling off period, but you can't call another ROFO immediately after a failed one.  There is a break that we have to take.   IIRC, Teck has 3 months to decide on our ROFO, and if they say 'Not interested' then we have 6 months from then to find a taker at that price.  Then if we fail, there's a 6 month(?) cooling of period before we can re-submit.  So from initiation of ROFO1 you could have to wait another 15 months before ROFO2 can be submited.    

Any real estate agent will tell you that it is a mistake to ignore market research, to ignore what the market will bear and to overprice your house listing, only to then have to humiliatingly discount the price from there.  Its bad optics.

The best way to get full market value is to get a broadly involved auction bidding environment going.  They need to start building relationships with Majors like yesterdecade!
